at0048::Scheimpflug Camera [A slit reflected light microscope, which has the ability to form an image of the back scattered light from the eye in a sagittal plane. Scheimpflug cameras are able to achieve a wide depth of focus by employing the “Sheimpflug principle” where the lens and image planes are not parallel with each other. Rotating Sheimplug cameras are able to generate three-dimensional images and calculate measurements of the anterior chamber of the eye. Corresponds to DICOM Code value 111626.]

at0051::Reflection-based corneal topographer [A reflection-based device that projects a pattern of light onto the cornea and an image of the reflection of that pattern from the tear film is recorded in one video frame. Light patterns include the circular mire pattern (Placido disc) and spot matrix patterns. Sequential scanning of light spots reflected from the corneal surface is also used requiring multiple video frames for recording. Corresponds to DICOM Code value 111946.]

at0052::Interferometry-based corneal tomographer [An Interference-based device that projects a beam of light onto and through the cornea. Light reflected from within the cornea is combined with a reference beam giving rise to an interference pattern. Appropriately scanned, this imaging is used to construct 3-dimensional images of the cornea from anterior to posterior surfaces. E.g., swept source OCT. Corresponds to DICOM Code value 111947.]

at0041::GCC (Ganglion cell complex) [Measurement approximating the distance related to the structure between the ILM and the outer border of the inner plexiform layer (IPL), called the ganglion cell complex (GCC). Corresponds to DICOM Code value 111926.]

at0042::Total retinal thickness (ILM to IS-OS) [Measurement approximating the distance related to the structure between the ILM and the inner-outer segment junction (IS-OS). Corresponds to DICOM Code value 111927.]

at0043::Total retinal thickness (ILM to RPE) [Measurement approximating the distance related to the structure between the ILM and the retinal pigment epithelium (RPE). Corresponds to DICOM Code value 111928.]

at0053::Total retinal thickness (ILM to BM) [Measurement approximating the distance related to the structure between the ILM and the Bruch's membrane (BM). Corresponds to DICOM Code value 111929.]
